Shangguan Zixiu

Shangguan Zixiu was an official of Wei under Ma Zun. He fought the Shu forces at the Battle of Tianshui in AD 228. Ma Zun became the target of one of Zhuge Liang's ploys and, ignoring the advice of his advisers, forced Jiang Wei to surrender to Shu. Some of his officers forsook this and allowed Shu into Tianshui. Ma Zun and Xiahou Wei tried to flee, but had no place to go and ended up surrendering.
